rad 128 can be broke into 64*2
square root of 64 is 8, times -5,
which leaves -40rad2
You would find the probability of getting an answer less than 10 by counting all of the possible outcomes, or numbers that are less than 10 and compare them to the total number of possible outcomes, or the total number of numbers. You would write the ratio of predicted outcomes to total possibilities.
The answer would be 4/9.
14 because - 11-17=-28. If you divide -28 by -2x you get 14
Hope this helps you, and good luck in the future :)
